When air temperatures fall below freezing point, sensitive crops can be injured, with significant effects on production. This publication discusses the distribution, economies, history, physical and biological aspects of frost damage, together with methods of protection. It contains a broad range of information but was mainly written to help growers to better understand freeze protection and to develop strategies to combat crop losses due to freezing. A related volume which focuses on concepts of probability and risk of frost damage is available separately (ISBN 9251053294).

The economic costs of frosts in agriculture and horticulture in many parts of the world can be very significant. Reports in the media include accounts on how frosts have devastated coffee crops in Brazil or in Papua New Guinea, and how frosts have seriously damaged the Florida citrus industry. Frost may cause losses in current harvests or a decline in future yields through more permanent damage to trees and bushes. Damaging frosts may occur as infrequent, short-term events with sub-zero temperatures or with unusually severe winter temperatures which extend over long periods. In this book we have aimed at providing a comprehensive review of recent advances in the area of frost research. The stimulus for writing this book has come from the recognition that there is a shortage of recent texts which deal exclusively with the bioclimatology of frost. Bioclimatology deals with the relations between climate and life and the present text is particularly concerned with the effects of low temperatures on plants. Our purpose has been to assist researchers, engineers, extension officers and students in understanding the physical aspects of frost occurrence and frost distribution as well as the biological and phenological aspects of frost damage and to provide an overview of direct and indirect methods of frost pro tection and prevention.

After serving for more than a decade as a hydraulic systems designer and regional manager for Motion Industries (div. Genuine Parts Co.), and then as president and chief hydraulics designer for RPT Industrial Technologies for another nine years, Steve studied and apprenticed for more than eight years under Dr. Rafael Guarga, Eng. prof. emeritus and president of the University of Uruguay. During that time, they collaborated and developed a new frost protection method of controlling cold air flows and draining accumulated cold air masses. An avid sportsman, over the last thirty-five years Steve has devoted much of his spare time to introducing underprivileged children to outdoor sports such as fishing and hunting through a nonprofit organization called the Annual Wild Game Feed. Steve now lives in Crestline, California, and enjoys weekends at the lake with his daughters. He is currently president and CEO of Shur Farms Frost Protection, a company specializing in managing cold air flows in vineyards and orchards worldwide. His speaking engagements range from Chihuahua, Mexico, to Ontario, Canada, and virtually every growing region in the United States. His articles and research in frost protection are regularly published in trade journals throughout the world.

Low temperature represents, together with drought and salt stress, one of the most important environmental constraints limiting the pro ductivity and the distribution of plants on the Earth. Winter survival, in particular, is a highly complex phenomenon, with regards to both stress factors and stress responses. The danger from winter cold is the result not only of its primary effect, i. e. the formation of ice in plant tissues; additional threats are presented by the freezing of water in and on the ground and by the load and duration ofthe snow cover. In recent years, a number of books and reviews on the subject of chilling and frost resistance in plants have appeared: all of these publications, however, concentrate principally on the mechanisms of injury and resistance to freezing at the cellular or molecular level. We are convinced that analysis of the ultrastructural and biochemical alterations in the cell and particularly in the plasma membrane during freezing is the key to understanding the limits of frost resistance and the mechanisms of cold acclimation. This is undoubtedly the immediate task facing those of us engaged in resistance research. It is nevertheless our opinion that, in addition to understanding the basic physiological events, we should be careful not to overlook the importance of the comparative aspects of the freezing processes, the components of stress avoidance and tolerance and the specific levels of resistance.
